Next, ask if you have the innate wit to mass produce simple boxes of toothpicks? Do you think a dozen top university professors could develop an effective method on their own?
Yes, I do. I was trained as a chemical engineer, and I do know how I’d do it. I wouldn’t use a team of “a dozen top university professors”: I’d put together a team of scientists and engineers. I might need a good materials scientist (which can be considered a branch of chemistry) to advise on the production of the little boxes and the glue for the labels. I’d need to pick appropriately trained individuals (technicians and engineers) to design and make the machines. If I wanted an automated system, I would need the help of people who design those because sadly that was never my strong point, but there are other chemical engineers who could do that bit themselves. I would design the overall process, and integrate systems where possible for maximum efficiency.
Nobody is saying that an individual can discover the whole of modern science and technology from scratch themselves, even as a group. It is cumulative: any work someone like me does into surface tension and bubble formation, for example, builds on work done by generations of scientists before us (Joseph Plateau for one, a Catholic, did wonderful work on soap films
after he went blind) and on more recent work, and relies on collaboration. But I can reproduce much of the work, and understand it, and use it to produce useful things. I can use recent theories of non-electrostatic properties of ions to tweak a mixture so that it foams more or less, whichever is most useful for the process in question.
I can use physical models, using science, to predict how different particles settle in a particular fluid, and from that design a settling tank for effluent as part of a process that cleans your sewage. Of course all wisdom comes from God, but that doesn’t mean science isn’t real. The level of conspiracy required for your theory, given that it is entirely possible to map out every stage of the process from research science to working technology, would require a significant proportion of the population to be in on it.
I guess, as a psychologist, you didn’t have to learn much actual science, let alone spend any time in industry learning how theory becomes practice. Are you also, perhaps, fairly young, and so only exposed to more recent technology that you cannot take to pieces, see how it works, and put it back together? Did you ever make your own circuits at school? Did you make simple motors? Did you ever make your own device for listening to vinyl records? There are all sorts of simple applied science experiments you can do, that bridge the gap between science and technology.
That psychology is still not really a full science doesn’t mean other areas are just pretending.
